Can by any one in several test or the multinomial improvement for determining in FR performance.Suitable standardized test comprises: the limiting oxygen index(LOI) (LOI) according to ASTM D2863 is measured; With test of various extinction time (time-to-extinguish) or flame spread (flame spread) test, such as be called FP-7 (further describing below) test and respectively Germany, France, Switzerland and Europe use DIN 4102 part 1, NF-P 92/501/4/5, SIA 183 or EN ISO 11925-2 tests.
If with not containing FR additive other similar foams compared with, limiting oxygen index(LOI) increase at least 0.5 unit of extruded polymer foams, preferably at least 1.0 units and more preferably at least 2 units, then improve and determined in LOI method.FR performance in LOI test can increase more than 8 units.Extruded polystyrene polymkeric substance containing flame-retardant additive of the present invention or multipolymer can show at least 21%, preferably at least 22% and more preferably at least 24% LOI.
Another kind of combustion testing measures the extinction time being called as FP-7, and its basis is by A.R.Ingram, and at J.Appl.Poly.Sci.1964, the method described in 8,2485-2495 is determined.This thermometrically is when polymer samples being exposed under given conditions the flame lighted, time when then being removed by ignition source needed for fray-out of flame.The short period instruction of the improvement of performance needed for fray-out of flame in this test.When polymer samples contains type i)-vi) in the flame-retardant additive of any one time, with compared with the polymer samples not containing FR additive, under this test, extinguish the required time be preferably reduced by least 1 second, be more preferably reduced by least 3 seconds, and be more preferably reduced by least 5 seconds.Extinction time about FR-7 test is less than 15 seconds aptly, is preferably less than 10 seconds, and more preferably less than 5 seconds.
At other extinction time or flame spread test case as in DIN 4102 part 1, NF-P92/501/4/5, SIA 183 and EN ISO 11925-2 test, improvement compared with the similar polymer samples not containing FR additive is indicated by " qualified " grade, or alternatively, by flame height reduce, flame out time and/or burning drop form instruction, this is described in detail in various testing method.
In these various tests, non-porous polymer may show different from foamed polymer.Similarly, specific flame-retardant additive can provide than benefit larger in porous polymer in non-porous polymeric objects system, or vice versa.Partly because poromeric higher surface-area, so porous polymer often shows the more challenging problem showed than non-porous polymer.
Other additive such as other flame-retardant additive, fire retardant auxiliary material, thermo-stabilizer, UV light stabilizing agent, nucleator, antioxidant, whipping agent, acid scavenger and tinting material can be comprised according to blend polymer of the present invention.
Blend polymer containing flame-retardant additive according to the present invention can be carried out melt-processed or solution processing to form multiple product.Foaming (porous) product is because they are interesting in the purposes paid close attention in the various building of fire performance and automobile application.Foamed-polymer products can have below 10pcf, more typically 1.5 to 5pcf and the tap density (bulkdensity) of 1.5 to 3pcf especially.As previously mentioned, the foamable polymer of the multipolymer of vinylaromatic polymer, butadiene polymer and vinylaromatic polymer and/or butadiene polymer makes us interested especially.Described foamable polymer can be used as, such as, insulation in building, family, automobile and other application and/or cushioning material.Foamable polymer of the present invention also can be used as added with padding or the underlayment of carpet.Also non-porous polymer can be prepared according to the present invention.
